GRAlN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 336,246, dated February16, 1886.

Application filed September 11, 1885. Serial No. l76,827. (No model.)

To all whom it may concern:

Be it known that I, ADDISON Lnx'r, a citizen of the United States ofAmerica, residing at Sleepy Eye, in the county of Brown and State ofMinnesota, have invented certain new and useful Improvements inGrain-Separators, of which the following is a specification, referencebeing had therein to the accompanying drawings.

to My invention has relation to grain-separators; and it consists in thenovel construction and combination of its parts, as hereinafterdescribed, and set forth in the claims.

In the accompanying drawings, Figure 1 is a front elevation of myinvention. Fig. 2 is side view of the lower parts. Fig. 3 is a detailview of one of the cups on the central wheel or hub. Fig. 4 is asectional view of the same on the line X X. Fig. 5 is a sectional viewof Fig. 1 on the line Y Y.

Between the two broad upright pieces, 1 and 2, I fasten ahopper, 3, intowhich is poured the grain to be screened. The bottom of this hopperrests on a board, 4, fastened horizontally to the uprights, and intowhich I place a slide-valve, 5, by which I can regulate the fiow ofgrain from the hopper or stop it altogether, as desired. To the bottomof the board 4, and immediately under the valve 5, I secure a trough orchute, 6, through which the grain runs, and from its open end falls intothe cups 7, attached to the central wheel or hub, 8, as

each cup is successively brought into the line of the grain fall.

Near the middle of a shaft, M, supported in the back of the separatorand extending through the front of the same, I affix a wheel or hub, 8.Around the periphery of this hub I insert arms 9, the same being rigidlysecured 0 in the said hub, and on the outer end of each of these arms Isecurea cup, 7. The centers of the said cups, in their revolution, passdirectly under the center of the chute 6. Thus the grain, as it falls,will strike inside of the 5 said cups, and not on the sides. In thefront or upper end of each cup 7 is secured ablock, 10, which forms aninclined plane from the bottom 11 of the cup to the upper edge, so thatthe grain may quickly and easily slide out of the cups when they reachtheir lowest level and fall on the double-inclined hopper,

consisting of two boards, 12 and 13, fastened to the uprights 1 and 2,their rear edges being higher than their front edges in order to givethe boards a cant toward the front. These boards also join at the middleof the frame, a short distance below the plane of their junction withthe sides. Thus the boards slant toward the center and front of theseparator and cause the grain to gather at the middle and front of thehopper, from which point it moves into a cylindrical wire screen orshaker, 14. through the interstices of which the cockle or other foreignmatter falls, while the grain passes on out of the front end and fallsinto a 6 receptacle.

The screener 1t is secured on a shaft, 15, which passes through itscenter, and is journaled at its rear end in a socket, eye, or any devicefor that purpose, attached to the bottom of the inclines 12 and 1.3. Theforward end of the shaft 15 is journaled in a crossbar, 16, which isfastened at its ends to two bars, 17 and 18, which are pivoted to theuprights 1 and 2. Near the outer ends of these bars 17 and 18 arepivoted two short bars, 19 and 20, their lower ends resting in notches21 of the bars 22, which are secured to the feet of the uprights 1 and 2and project forward from the same. This arrangement of the bars 1.6 l718 8o 19 20 and the notched bars 22 is for the purpose of grading theslant or incline of the screen so that the grain will not run out toofast nor too slow.

The screen 11 is revolved by means of a belt, 23, passing over a pulley,24, rigidly secured on the outer end of the shaft M, and around a smallpulley, 25, rigidly secured on the inner end of the shaft 15.

The operation of my machine is as follows: 0 The grain to be cleaned ispoured into the hopper 3. It passes thence through the chute 6 and fallsinto the cups 7, which causes the hub 8 to revolve with them, which, inturn, revolves the pulley 24, and this, by means of the belt 23,revolves the small pulley 25, the shaft 15, and wire screen 14., whichis attached to the shaft by braces.
